Abstract

We present results on disordered amorphous films which are expected to undergo a field-tuned superconductor-insulator transition. Based on resistance and I-V characteristics, we find evidence of a low field metal-to-superconductor transition. This transition is characterized by a rapid drop in resistance and discontinuities in the I-V curves. The metallic phase just above the transition seems to be an unusual, non-Fermi metal and the superconducting phase seems to be a true zero resistance state.
